These days, you can get a positively stupid amount of horsepower for relatively cheap, especially if you drive one of the Big Three’s forced induction muscle cars. Turn $55,000 of your hard-earned money over to Hennessey Performance Engineering, and they’ll transform your Chevrolet Camaro ZL1 1LE with their beastly 1,000-horsepower Exorcist package, for instance.
But any time you turn up the wick on a factory car’s performance, you take on a good amount of risk. OEMs engineer their cars with a durability margin built-in, but as it’s never clear exactly how great the margin is, it’s very possible to exceed it.
Enter Callaway Cars, which builds the “most powerful Camaro you can buy new with a full factory warranty.”
